[Request] Formula E round 2, Marrakech Eprix 2019

There's a simpler way that even works via the embedded player.

start playing the video

Access "view page info" (this can be found in the right click menu, though I think it's also be located in the standard browser menu and such)

Click the "media" tab

Find your video from the list

Save the file

Note that, it can be a bit difficult to determine which is the correct video file, so the safest way to do this is to first right click on the video itself, select the 3rd Russian-text option, highlight and select the embedded URL part (in this case https://my.mail.ru/video/embed/7574382818877246804 ), and then follow the steps I layed out above.
